Description

Technical Field

[0001] This invention relates to the field of screening devices, specifically to a screening device for the production quality of fried peanuts. Background Technology

[0002] In the production of fried peanuts, cleaning and quality screening of raw peanuts is a crucial preliminary step. Currently, the widely used method in the industry is water separation, which utilizes the density difference between plump peanuts and shriveled, moldy, or other substandard peanuts: when peanuts are poured into a water tank, plump peanuts will sink to the bottom, while substandard peanuts will float on the surface, thus achieving initial separation.

[0003] Patent publication number CN114054193B relates to the field of screening device technology, including a hollow pressure-bearing shell. The pressure-bearing shell includes: a top with an installation port, a bottom with a sand discharge port, and a side wall located between the top and the bottom. A vortex injection port is provided on the side wall, and the vortex injection port is connected to an inlet accelerating conduit for rotating and conveying sewage into the pressure-bearing shell. A central guide pipe is provided inside the pressure-bearing shell, and a guide cone plate is provided between the central guide pipe and the sand discharge port. The guide cone plate has guide holes. This invention can generate vortex flow in sewage and then use centrifugal force to separate steel sand, and can further remove suspended impurities in the steel sand. It uses mechanical methods to separate and recover steel sand from sewage, and has the advantages of high separation efficiency, simple and reliable structure, and convenient operation.

[0004] The aforementioned patent utilizes mechanical methods to separate and recover steel shot from wastewater, offering advantages such as high separation efficiency, simple and reliable structure, and convenient operation. However, traditional devices typically employ fixed push plates or simple scrapers for unidirectional pushing, which cannot effectively lift the peanuts during the return stroke. This easily leads to the re-bringing of light peanuts already pushed to the collection area back to the screening area, causing repeated screening or even secondary mixing, severely compromising the uniqueness of the sorting effect. Furthermore, the feed inlet of older equipment is often permanently open or manually controlled. If feeding continues during the pushing process, newly added peanuts will disrupt the water flow, impacting the light peanuts being pushed and disrupting their trajectory. This results in some unqualified peanuts failing to enter the collection channel and remaining in the screening tank. This disorder in screening and feeding not only reduces sorting efficiency but also leaves shriveled and damaged peanuts mixed in after screening, severely affecting the quality and taste of the final fried product. It fails to guarantee continuous automated operation of the production line, increases the cost of subsequent manual re-inspection, and significantly reduces the actual efficiency and economic benefits of the screening device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quality screening device for fried peanut production, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quality screening device for fried peanuts, comprising a screening tank, wherein the screening device further comprises:

[0017] According to the above technical solution, the pushing device further includes: the side of the key near the push plate is set as an inclined surface; an elastic element is provided between the key and the sliding block; the elastic element is provided to drive the key to move in the direction of the push plate; and a torsion spring is provided between the opening and closing plate and the discharge frame; the torsion spring is provided to drive the opening and closing plate to reset.

[0018] According to the above technical solution, the retrieval device includes a pull rod, a gear, a push plate, and a collection plate. The pull rod is slidably embedded in the inner wall of the screening tank. The push plate is rotatably installed in the inner wall of the screening tank. The gear is rotatably embedded in the inner wall of the screening tank and is fixedly connected to the rotating shaft of the push plate. Teeth are fixedly installed on the side of the pull rod near the gear, and the pull rod meshes with the gear. The collection plate is slidably installed on the outer wall of the push plate. The collection plate actively extends away from the push plate, which greatly increases its effective working area and coverage on the water surface, and can intercept and accommodate more floating unqualified peanuts at once.

[0019] According to the above technical solution, the retrieval device further includes an auxiliary rod, a stop rod, a slide rod, and a push block. The auxiliary rod slides through the surface of the push plate, and a sliding groove is provided on the side of the auxiliary rod near the discharge frame two. The slide rod is fixedly installed on the side of the collection plate near the auxiliary rod, and the slide rod contacts the inner wall of the sliding groove. The push block is fixedly installed on the inner wall of the screening tank near the auxiliary rod, and the stop rod is fixedly installed on the side of the screening tank near the push plate. The movement of the auxiliary rod can actively push the peanuts adhering to the surface of the push plate off, ensuring that all collected materials can be sent into the discharge frame two.

[0020] According to the above technical solution, the retrieval device further includes an elastic element two between the collecting plate and the pushing plate. The elastic element two is provided to push the collecting plate to move away from the pushing plate. The side of the push block near the auxiliary rod is set as an inclined surface.

The slider is slidably installed on the inner wall of the second discharge frame. One end of the connecting rod is rotatably connected to the slider, and the other end of the connecting rod is rotatably connected to the rotating disk. The feeding plate is rotatably installed at the bottom of the inner wall of the second discharge frame. The feeding plate is rotatably connected to the slider. The rotation of the feeding plate will push the peanuts placed on the surface into a deeper position in the second discharge frame, so that unqualified peanuts are discharged from the discharge port.

[0022] According to the above technical solution, the unblocking device also includes a pressure block and a pressure rod. The pressure block is slidably installed on the inner wall of the second discharge frame, and the pressure rod is fixedly installed on the side of the pressure block away from the second discharge frame. The side of the pressure block near the slider is set as an inclined surface. When the pressure block moves downward, it will drive the pressure rod to move. The movement of the pressure rod will unblock the inside of the second discharge frame, preventing excessive peanuts from clogging the inside of the second discharge frame.

[0023] According to the above technical solution, an elastic element three is provided between the sliding rod and the telescopic key. The elastic element three is provided to drive the telescopic key to move downward. The side of the telescopic key near the pull rod is set as an inclined surface.

A torsion spring three is provided between the feeding plate and the discharge frame two. The torsion spring three is provided to drive the feeding plate to reset.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. In this invention, when the push plate moves towards the direction close to the discharge frame two, the push plate will contact the inclined surface inside the chute. The push plate will then be pushed upward by the inclined surface. During the pushing stroke, the push plate is in a low position to push the floating peanuts, while during the return stroke, it is raised to avoid pushing the already pushed material back. This single-stroke working mechanism ensures the uniqueness and effectiveness of the screening direction. The opening and stopping of the feeding action of the opening and closing plate is directly controlled by the reciprocating screw and sliding block, which makes the replenishment of peanut raw materials and the screening in the screening tank orderly. Feeding is only triggered when the push plate is in the return stroke, avoiding interference caused by adding new material during the process of pushing unqualified peanuts, and ensuring the orderliness and efficiency of the screening process.

[0026] 2. In this invention, the rotation of the push plate causes the collection plate to move, extending it away from the push block to increase the peanut catching effect. The active extension of the collection plate away from the push block greatly increases its effective working area and coverage on the water surface, enabling it to intercept and accommodate more floating unqualified peanuts at once, significantly increasing the catching volume of a single action. This avoids the problem of peanuts easily slipping or overflowing from both sides during the pushing process of the flat plate. The movement of the auxiliary rod can actively push the peanuts adhering to the surface of the push plate off, ensuring that all collected materials can be sent into the discharge frame two. This prevents residues from falling back into the screening tank when the equipment is reset, mixing with the next batch of qualified peanuts to be screened, thus ensuring the independence of each screening operation and the purity of the results.

[0027] 3. In this invention, the movement of the slider pulls the feeding plate to rotate. The rotation of the feeding plate pushes the peanuts placed on the surface into the inner part of the second discharge frame, allowing unqualified peanuts to be discharged from the discharge port. This prevents peanuts from accumulating on the surface of the feeding plate and causing blockage in the second discharge frame. When peanuts collected at one time are poured into the second discharge frame, they may not be able to slide out of the outlet immediately by their own weight. The timed rotation of the feeding plate provides a boost, pushing the peanuts from the surface of the feeding plate into the inclined channel inside or directly to the final discharge port. This intermittent and forced pushing effectively breaks the blockage that may form at the outlet, ensuring a smooth discharge process. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-7 One embodiment of the present invention is: a quality screening device for fried peanut production, which includes a screening tank 1, and the screening device further includes:

[0039] Feeding trough 2 is fixedly installed on the top of screening tank 1. Feeding trough 2 is connected to screening tank 1. Screening tank 1 has a discharge port on its outer wall. A discharge frame 3 is rotatably installed on the outer wall of the discharge port. Screening tank 1 has a water inlet on its outer wall.

[0040] The second discharge frame 4 is fixedly installed on the side of the screening tank 1 away from the first discharge frame 3. The second discharge frame 4 is connected to the screening tank 1, and the bottom of the second discharge frame 4 has a discharge port.

[0041] Motor 5 is fixedly installed on the side of the screening tank 1 near the discharge frame 4. The output end of motor 5 rotates through the outer wall of the screening tank 1.

[0042] The reciprocating screw 6 is rotatably installed on the inner wall of the screening tank 1, and the reciprocating screw 6 is fixedly connected to the output end of the motor 5;

[0043] The sliding block 7 is slidably installed on the circumferential surface of the reciprocating lead screw 6, and the inner wall of the sliding block 7 is slidably installed with a push plate 8;

[0044] The pushing device used to push the unqualified peanuts floating on the liquid surface into the discharge frame 4 is set on the inner wall of the screening tank 1;

[0045] A scooping device for scooping up peanuts floating on the surface of a liquid is installed on the inner wall of the screening tank 1;

[0046] A clearing device for clearing the inside of the discharge frame 4 is installed inside the screening tank 1.

[0047] The pushing device includes a key 9, a push rod 10, and a connecting rod 11. A sliding groove is provided on the inner wall of the screening tank 1. The push plate 8 contacts the inner wall of the sliding groove. The key 9 slides through the inner wall of the sliding block 7. A slot is provided on the side of the push plate 8 near the key 9. The shape of the key 9 matches the slot. One end of the connecting rod 11 is rotatably connected to the key 9. The push rod 10 is rotatably installed on the other end of the connecting rod 11.

[0048] The pushing device also includes an opening and closing plate 12 and a telescopic plate 13. The opening and closing plate 12 is rotatably installed on the inner wall of the discharge frame 4, and the telescopic plate 13 is fixedly installed on the bottom of the opening and closing plate 12. The movable end of the opening and closing plate 12 is set as an inclined surface on the side near the push plate 8.

[0049] The pushing device also includes a sloped side of the key 9 near the push plate 8, an elastic element between the key 9 and the sliding block 7, the elastic element being provided to drive the key 9 to move toward the push plate 8, and a torsion spring between the opening and closing plate 12 and the discharge frame 3, the torsion spring being provided to drive the opening and closing plate 12 to reset.

[0050] In this embodiment, before frying peanuts, they need to be washed and unqualified peanuts need to be screened out. During washing and screening, clean water needs to be poured into the screening tank 1 for soaking. During the soaking process, shriveled and bad peanuts will float on the surface of the liquid due to their lower gravity, while plump peanuts, with their dense structure and small internal gaps, have a density greater than water and will sink to the bottom. Peanuts floating on the surface will be pushed into the discharge frame 4 by the push plate 8 for collection, while peanuts that sink to the bottom will be discharged with the water flow. When in use, the motor 5 will start, which will drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 will drive the sliding block 7 to slide. When the sliding block 7 slides, it will drive the push plate 8 to move. The movement of the push plate 8 will push the peanuts floating on the surface toward the discharge frame. When the push plate 8 moves in the direction of the discharge frame 24, it will move along the chute inside the screening tank 1. When the push plate 8 moves closer to the discharge frame 24, it will contact the inclined surface inside the chute. The push plate 8 will then be pushed upward by the inclined surface. The upward movement of the push plate 8 will cause the slot to move. When the position of the slot coincides with the key 9, the key 9 will be inserted into the slot. The key 9 will limit the push plate 8. When the reciprocating screw 6 drives the sliding block 7 to move back to its original position, the sliding block 7 will drive the push plate 8 to move back to its original position. When the push plate 8 moves back to its original position, it will not contact the peanuts on the liquid surface, thus avoiding pushing the peanuts away from the discharge frame 24. When the push plate 8 moves back to its original position, it will push the push rod 10 to contact the inner wall of the screening tank 1. The push rod 10 will then be squeezed and pushed closer to the push plate 1. When the pusher plate 8 moves, the pusher 10 moves, which in turn pushes the connecting rod 11 to move. The connecting rod 11 then pushes the key 9 to move. The key 9 releases the limit on the pusher plate 8, causing it to move downwards and contact the peanuts. During the pushing stroke, the pusher plate 8 is in a low position to push the floating peanuts, while during the return stroke, it is raised to avoid pushing back the already pushed material. This single-stroke working mechanism ensures the uniqueness and effectiveness of the screening direction. Through the triggering mechanism composed of the pusher 10 and the connecting rod 11, the pusher plate 8 is automatically unlocked when it returns to the origin, allowing it to descend to the working position and prepare for the next push. The entire process is smooth and highly automated. When the sliding block 7 moves towards the discharge frame 4, it contacts the inclined surface of the telescopic plate 13. The movable end of the telescopic plate 13 moves towards the fixed end of the telescopic plate 13. When the sliding block 7 moves back to its original position, it pushes the telescopic plate 13 to move. The movement of the telescopic plate 13 drives the opening and closing plate 12 to rotate. The rotation of the opening and closing plate 12 opens the seal on the discharge frame 3, allowing the peanuts inside the discharge frame 3 to fall into the screening tank 1. When the sliding block 7 is not in contact with the telescopic plate 13, the opening and closing plate 12 is driven by the torsion spring to reset and seal the discharge frame 3. The opening and stopping of the feeding action of the opening and closing plate 12 is directly controlled by the reciprocating screw 6 and the sliding block 7, making the replenishment of peanut raw materials and the screening in the screening tank 1 orderly. Feeding is only triggered when the push plate 8 is in the return stroke, avoiding interference caused by adding new material during the process of pushing unqualified peanuts.This ensured the orderly and efficient nature of the screening process.

[0051] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the fried peanut production quality screening device further includes a scooping device and a clearing device.

[0052] The retrieval device includes a pull rod 21, a gear 22, a push plate 23, and a collection plate 24. The pull rod 21 is slidably embedded in the inner wall of the screening tank 1. The push plate 23 is rotatably installed in the inner wall of the screening tank 1. The gear 22 is rotatably embedded in the inner wall of the screening tank 1. The gear 22 is fixedly connected to the rotating shaft of the push plate 23. The pull rod 21 has teeth fixedly installed on the side near the gear 22. The pull rod 21 meshes with the gear 22. The collection plate 24 is slidably installed on the outer wall of the push plate 23. The collection plate 24 actively extends to the side away from the push block 28, which greatly increases its effective working area and coverage on the water surface, and can intercept and accommodate more floating unqualified peanuts at once.

[0053] The scooping device also includes an auxiliary rod 25, a stop rod 26, a slide rod 27, and a push block 28. The auxiliary rod 25 slides through the surface of the push plate 23. A sliding groove is provided on the side of the auxiliary rod 25 near the discharge frame 24. The slide rod 27 is fixedly installed on the side of the collecting plate 24 near the auxiliary rod 25. The slide rod 27 contacts the inner wall of the sliding groove. The push block 28 is fixedly installed on the inner wall of the screening tank 1 near the auxiliary rod 25. The stop rod 26 is fixedly installed on the side of the screening tank 1 near the push plate 23. The movement of the auxiliary rod 25 can actively push the peanuts adhering to the surface of the push plate 23 off, ensuring that all collected materials can be sent into the discharge frame 24.

[0054] The retrieval device also includes an elastic element 2 between the collecting plate 24 and the pushing plate 23. The elastic element 2 is provided to push the collecting plate 24 to move away from the pushing plate 23. The side of the push block 28 near the auxiliary rod 25 is set as an inclined surface. A torsion spring 2 is provided between the pushing plate 23 and the screening tank 1. The torsion spring 2 is provided to drive the pushing plate 23 to reset.

[0055] The unblocking device includes a pull rod 31, a sliding rod 32, a telescopic key 33, a rotating disk 34, a connecting rod 35, a connecting rod 36, a slider 37, and a feeding plate 38. The pull rod 31 is fixedly installed on the side of the push plate 23 away from the discharge frame 4. The sliding rod 32 is slidably installed on the inner wall of the discharge frame 4. The telescopic key 33 slides through the outer wall of the sliding rod 32. The rotating disk 34 is rotatably installed on the inner wall of the discharge frame 4. One end of the connecting rod 35 is rotatably connected to the rotating disk 34, and the other end of the connecting rod 35 is rotatably connected to the sliding rod 32. The slider 37 is slidably installed on the inner wall of the discharge frame 4. One end of the connecting rod 36 is rotatably connected to the slider 37, and the other end of the connecting rod 36 is rotatably connected to the rotating disk 34. The feeding plate 38 is rotatably installed at the bottom of the inner wall of the discharge frame 4. The feeding plate 38 is rotatably connected to the slider 37. When the feeding plate 38 rotates, it pushes the peanuts placed on the surface into a deeper position in the discharge frame 4, causing unqualified peanuts to be discharged from the discharge port.

[0056] The unblocking device also includes a pressure block 39 and a pressure rod 391. The pressure block 39 is slidably installed on the inner wall of the discharge frame 4, and the pressure rod 391 is fixedly installed on the side of the pressure block 39 away from the discharge frame 4. The side of the pressure block 39 closest to the slider 37 is set as an inclined surface. When the pressure block 39 moves downward, it will drive the pressure rod 391 to move. The movement of the pressure rod 391 will unblock the inside of the discharge frame 4 and prevent excessive peanuts from clogging the inside of the discharge frame 4.

[0057] An elastic element 3 is provided between the sliding rod 32 and the telescopic key 33. The elastic element 3 is provided to drive the telescopic key 33 to move downward. The side of the telescopic key 33 near the pull rod 31 is set with an inclined surface. The inclined surface of the telescopic key 33 is provided to facilitate the pull rod 31 to push the telescopic key 33 to move upward. A torsion spring 3 is provided between the feeding plate 38 and the discharge frame 4. The torsion spring 3 is provided to drive the feeding plate 38 to reset.

[0058] In this embodiment, when the push plate 8 moves upward along the inclined surface of the slide groove, it contacts the pull rod 21. The push plate 8 then pushes the pull rod 21 upward. The upward movement of the pull rod 21 drives the gear teeth to move, which in turn drives the gear 22 to rotate. The rotation of the gear 22 drives the push plate 23 to rotate, which in turn drives the collecting plate 24 to move. The collecting plate 24 then extends away from the push block 28, increasing the peanut catching effect. The active extension of the collecting plate 24 away from the push block 28 greatly increases its effective working area and coverage on the water surface, enabling it to intercept and accommodate more floating unqualified peanuts at once. This significantly increases the catching amount per action and avoids the problem of peanuts easily slipping or overflowing from both sides during the pushing process of the flat plate. When the collecting plate 24 rotates, it will come into contact with the baffle 26. The baffle 26 will then exert a backward force on the collecting plate 24, causing it to move closer to the sliding rod 27. This movement of the collecting plate 24 will drive the sliding rod 27 to move, which in turn will press the auxiliary rod 25 to move closer to the discharge frame 24. The movement of the auxiliary rod 25 will push the peanuts adhering to the surface of the push plate 23 into the discharge frame 24. The movement of the auxiliary rod 25 can actively push the peanuts adhering to the surface of the push plate 23 off, ensuring that all collected materials are sent into the discharge frame 24. This prevents residues from falling back into the screening tank 1 when the equipment resets and mixing with the next batch of qualified peanuts to be screened, thus ensuring the independence of each screening operation and the purity of the results.

[0059] When the push plate 23 rotates upward, it pushes the collected peanuts into the discharge frame 4. The peanuts falling into the discharge frame 4 are placed on the surface of the feeding plate 38. When the push plate 23 rotates, it drives the pull rod 31 to move. The pull rod 31 moves and contacts the inclined surface of the telescopic key 33. The pull rod 31 then pushes the telescopic key 33 upward to avoid obstruction. When the push plate 23 resets, it drives the pull rod 31 to reset. The reset pull rod 31 contacts the telescopic key 33, which then pushes the telescopic key 33 to move. The telescopic key 33 moves and drives the sliding rod 32 to move. The sliding rod 32 moves and drives the connecting rod 35 to move. The connecting rod 35 moves and drives the rotating disk 34 to rotate. The rotating disk 34 moves and drives the connecting rod 36 to move. The connecting rod 36 moves and drives the slider 37 to move. The slider 37 moves and drives the feeding plate 38 to rotate. The rotation of the feeding plate 38 will move the peanuts onto the surface of the feeding plate 38. The peanuts placed on the surface are pushed into the inner part of the discharge frame 4, so that unqualified peanuts are discharged from the discharge port. This prevents peanuts from accumulating on the surface of the feeding plate 38 and causing blockage in the discharge frame 4. When peanuts collected at one time are poured into the discharge frame 4, they may not be able to slide out of the outlet immediately by their own weight. The peanuts are pushed from the surface of the feeding plate 38 into the inclined channel inside the feeding plate 38 or directly to the final discharge port by the timed rotation of the feeding plate 38. This intermittent and forced pushing effectively breaks the blockage that may form at the outlet and ensures a smooth discharge process. When the slider 37 moves, it will contact the inclined surface of the pressure block 39. The movement of the slider 37 will push the pressure block 39 downward. The downward movement of the pressure block 39 will drive the pressure rod 391 to move. The movement of the pressure rod 391 will clear the inside of the discharge frame 4 and prevent too many peanuts from blocking the inside of the discharge frame 4, so that unqualified peanuts cannot be discharged.
